It is important to use the correct valve type for your rim; using undersized valves (for example Presta type on Schrader width holes) can lead to the tearing at the valve hole and puncturing.
Please note:

Traditional (woods) valves can be replaced be Schrader type valves.

Regina (Italian) valves can be replaced by Presta type valves.

Which length of valve do I need?

A variety of valve lengths are available to accommodate shallow to deep section rims. Before purchasing your tubes make sure that you choose the correct valve length, leaving enough space for you to connect a pump. Generally, 48mm valves are long enough for most square section and low profile rims. Deep section rims may require 60mm valves, extenders are also available for converting standard length valves or for use with extra deep section rims. If you�re unsure which length valve you need, please consult your rim manufacturer�s guidelines.

What�s the correct innertube size for my tyre?

The best way to check to this is to use the size conversion chart in the downloadable PDF below. There will normally be two size information markings on the sidewall of your tyre. This should be in one of three different size standards. Just choose the size tube that corresponds to the size on the sidewall. For example: a 18/25-622 tube will fit 18c, 20c, 23c and 25c width, 622mm (700c) diameter tyres.
